MILITARY SHOULDER-ARM.

Specification of Letters Patent.

Patented July 25, 1916.

Application filed November 8, 1915. Serial No. 60,177.

To all whom it may concern:

Be it known that I, THOMAS C. JOHNSON, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Military Shoulder-Arms; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in

Figure 1 a broken view in right hand elevation of a military shoulder-arm con structed in accordance with my invention. Fig. 2 a reverse plan view thereof. Fig. 3 a corresponding view, with the box-magazine and forestock-lock removed. Fig. i a detached view in side elevation of the forestock-lock. Fig. 5 a plan view thereof. Fig. 6 a detached view in front elevation of the receiver-extension. Fig. 7 a view in rear elevation of the forestock.

My invention relates to an improvement in military shoulder-arms, the object being to provide simple and effective means for holding the forestock of such arms against forward displacement without imposing any strain whatever upon the gun-barrel.

With these ends in view, my invention consists in a military shoulder-arm having certain details of construction as will be hereinafter described and pointed out in the claim.

In carrying out my invention as herein shown, I employ a hook-like forestock-lock 2 provided at its forward end with an upstanding lug 3 having its forward face rounded and its rear face beveled, and entering a corresponding vertical recess l formed in the lower face of the rear end of the forestock 5 which is also formed in its lower face with a longitudinal clearance recess 6 for receiving the shank or body-portion of the lock, and with a recess 7 for receiving a forwardly projecting lug 8 made integral with the lower end of a receiver-extension 9 which is secured to the receiver 10 and forms an extension of the forward end thereof. As thus constructed and arranged the forestock-lock 2 is exposed, as it were, upon the outside of the gun and may be inserted and removed after the gun has been assembled.

For securing the forestock-lock 2 to the receiver-extension 9, and hence to the receiver 10, I employ a screw 11 passing upward through the rear end of the lock into the lug 8, as clearly shown in Fig. 1. Upon the upper face of its rear end, the lock 2 is formed with a circular locking-boss 12 entering a corresponding recess 13 in the lower face of the lug 8, the said boss being concentric with the screw 11 and relieving the same of strain. Under the construction described, the forestock 5 is firmly held against longitudinal forward movement by the upstanding lug 3 of the lock 2, whereby the forestock is held in place without imposing any strain whatever upon the gunbarrel 14: the rear end of which is formed with a threaded shank 15 which is screwed into acorrespondingly threaded opening in the upper portion of the receiver 10. As shown, the box magazine 16 is furnished with a forward tang 17 receiving a screw 18 extending upward through it into a rearwardly extending lug 19 formed integral with the rear face of the lower end of the receiver-extension 9 as clearly shown in Fig. 3.

So far as my present invention is concerned the receiver-extension might be made integral with the receiver.

1 claim In a military shoulder-arm, the combination with the receiver thereof, of a receiverextension having a forwardly projecting lug, a forestock formed in its lower face with a locking-recess, and a forestoclr-lock entering the said recess and having its rear end fastened to the said lug.
